"…Let us watch and BE SOBER. For those who sleep, sleep at night, and those who get drunk are drunk at night. But let us who are of the day BE SOBER…" (1 Thessalonians 5:6-8) Sober – Nepho: "to be free from the influence of intoxicants." (Vine's Expository Dictionary of New Testament Words)

But in New Zealand (where the drinking age was lowered from 20 to 18 in 1999),
“A study found that after the drinking age was lowered to 18, there was a significant increase in traffic crashes among youth affected by the law change. The study found that the rate of traffic crashes and injuries to 18- to 19-year-old males increased 12 percent and increased 14 percent for males aged 15 to 17 comparing 4 years before and after New Zealand lowered the MLDA to 18. For females, the effect was even greater—rates increased 51 percent for 18- to 19-year-olds and 24 percent for 15- to 17-year-olds. The study estimated that 400 serious injuries and 12 deaths could be prevented each year among 15- to 19-year-olds if the nation raises the MLDA back to 21.”
